Begonia plant named ‘Innbolora’

ABSTRACT

A new and distinct cultivar of  Begonia  plant named ‘Innbolora’, characterized by its compact and mounded to trailing plant habit; freely branching habit; dense and bushy growth habit; dark green-colored leaves; and numerous single flowers that are bright orange in color.

Botanical designation: Begonia hybrida.

Cultivar denomination: ‘Innbolora’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia hybrida and hereinafter referred to by the name ‘Innbolora’.

The new Begonia plant is a product of a planned breeding program conducted by the Inventor in Gensingen, Germany. The objective of the breeding program was to develop new compact Begonia cultivars with attractive single flowers.

The new Begonia plant originated from a cross-pollination made by the Inventor in September, 2003 of Begonia×tuberhybrida ‘Elserta’, not patented, as the female, or seed, parent with an unnamed selection of Begonia boliviensis, not patented, as the male, or pollen, parent. The new Begonia was discovered and selected by the Inventor as a single plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Gensingen, Germany in September, 2004.

Asexual reproduction of the new Begonia plant by vegetative cuttings in a controlled greenhouse environment in Gensingen, Germany since October, 2004, has shown that the unique features of this new Begonia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Begonia have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Innbolora’. These characteristics in combination distinguish ‘Innbolora’ as a new and distinct cultivar of Begonia:

-   -   1. Compact and mounded to trailing plant habit.     -   2. Freely branching habit; dense and bushy growth habit.     -   3. Dark green-colored leaves.     -   4. Numerous single flowers that are bright orange in color.

Plants of the new Begonia differ from plants of the female parent, ‘Elserta’, primarily in flower form as plants of ‘Elserta’ have double flowers.

Plants of the new Begonia differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Begonia are more compact than and not as         trailing as plants of the male parent selection.     -   2. Plants of the new Begonia are more freely branching than         plants of the male parent selection.     -   3. Plants of the new Begonia have larger flowers than plants of         the male parent selection.

Plants of the new Begonia can also be compared to plants of the Begonia×tuberhybrida ‘Bonfire’, disclosed in U.S. Plant Pat. No. 15,108. In side-by-side comparisons conducted in Gensingen, Germany, plants of the new Begonia differed from plants of ‘Bonfire’ in the following characteristics:

-   -   1. Plants of the new Begonia were more compact and mounded than         plants of ‘Bonfire’.     -   2. Plants of the new Begonia were more freely branching and         denser than plants of ‘Bonfire’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Begonia, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Begonia plant.

The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘Innbolora’ grown in a container.

The photograph at the top of the sheet is a close-up view of typical flowers and leaves of ‘Innbolora’.

DETAILED BOTANICAL DESCRIPTIONS

Plants used for the aforementioned photographs and following observations and measurements were grown in Bonsall, Calif. in one-gallon containers and under commercial practice in a shaded polyethylene-covered greenhouse during the late summer. During the production of the plants, day temperatures ranged from 18° C. to 35° C., night temperatures ranged from 10° C. to 24° C. Plants used for the photographs and the description were pinched one time and were twelve weeks from planting. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
